Pistols on Top Of The Pops?

I seem to recall the Pistols doing Pretty Vacant on Top of the Pops and thinking how they were like a slightly grubby Bay City Rollers - grinning drummer, black spikey dumb looking guitarist, mature above-it-all guitarist, and microphone juggling beting it out singer and a sing-along chorus. Does this still exist in some form, preferably with inane DJ intro and outro? Can anyone direct me to it?
